DEMOUNTABLE WHEEL.

1 'o att whom t may concern:

Be it known that I, ISAAC N. WHITE, a citizen of the United States,residing at Chicago, in the county. of Cook and State of Illinois, haveinvented certain new and use- A ful Improvements in Demountable Wheels,

of which the following is a specification.

This invention relates to a vehicle wheel which is demountable from itshub to permit the interchange of wheels, such, for example, as theWheels of an automobile, making it possible' to substitute an extraWheel on which is an inflated tire for one which has failed in use, bysimply removing the Wheel .from the hub and placing the extra wheelthereon. The invention consists in the novel construction, combinationand arrangementvof the parts.

In the accompanying drawing, Figure 1 is a sectional View of a portionof a wheel and of the hub thereof, embodying this invention; F ig. 2 isa side elevation of the parts shown in Fig. 1; and Fig. 3 shows anextended fastening ring for a speedometer gear attach-ment. y

The construction shown and described is tha-tcommonly employed in theFord automobile, although, of course, it may have a gleneral applicationto other Wheels of this c ass. l

A wheel hub member l is formed with a `central perforation into which anaide (not -'shown) for the wheel is inserted, and comf prises a 'recess2 for a bearing ring 3 1n which are bearings 4:, held in place by a ring5 and protected by a Washer'e. Extending from the body of the member l,is a flange 7 which is ordinarily -formed with Unthreaded perforations 8through which fasteningmembers are inserted to hold a wheel properinposition. The Wheel comprises spokes 9. which are connected togetheraround the center with a central peroration of suliicient size so thatthe connected portion of the spokes with the central perforation, may bepassed over the hub member 1 and pressed against the flange he connectedspokes are formed with perforations 10 registering with the perforations8 of the flange 7, so that the fastening members ordinarily employed areinsertible through the holes in the flange 7 and through the holes 10 ofthe wheel. At 'the outer side is a perforated plate 11, andthe fasteningmembers ordinarily employed are insertcd first through this platel 11,'then Specification of Letters Patent.

through the perforations in the wheel, and through the perforations ofthe flanged plate 7 With fastening nuts applied on the inside.

Instead of inserting the fastening devices from the outside of theWheel, a metal ring 12 is provided in which are threaded perforations 13registering with the perforations This ring has such an internaldiameter that it may be placed tightly against the flange 7 `andfastening bolts 14 are then inserted through the perforations 8 and theheads are threaded up tightly against the flange, drawing the ring 12tightly against the flange on the other side thereof, in which ing anindentation 15 with a prick punch at the inside of the ring 12 toprevent the bolt 14: turning therein, or in any other suitable manner.This construction holds the position it is held by Inakfastening bolts14; rigidly in place with respect tothe hub member 1, even though thewheel be entirely removed, and there is no danger of any one or moreofthe bolts being displaced or getting lost in changing the wheels'. areprovided with nuts 16 Which are threaded in place against the plate 11at the outer side of the Wheel, thereby holding the Wheel rigidly/"ginplace between the two meta-l plates. The outer plate 11 may be securedtothe Wheel by fastening screws 17.

. The bolts 14 are uniformly threaded .almost theiry entire length, sothat the ring 12 may be drawn up tightly against the flange 7. If athreaded enlarged portion were provided near the headed endforattachment to the ring 12, and the outer end of the bolt were threadedfor the nut 16, the same result would be obtained but it would be a moreexpensive construction.

A speedometer gear 18 is usually applied to one of the front Wheels, andfor this Wheel a ring 12 is provided similar to the ring 12, whichextends beyond the edge of the flange 7, into which portion a fasteningscrew 19 is threaded, the screw also extending through the gear 18 andthrough a spacing Washer 20 for holding the gear 18 in the proper place.

In order to change a wheel, it is only t 1n place by the ring 12; lthensubstitute theV extra wheel and replace the nuts.

I claim.: 1.,In a demountable wheel, a wheel hub member having anextending flange with unthreaded perforations, a metal ring havi ingthreaded perforations registering with the said other perforations,bolts inserted.

through the registering perforations for drawing the ring tightl;7against the ange,=

and means for preventing the removal of the bolts. l 2. In a demountableWheel, the combina-1 tion with a hub member having a perforated flange,of a ring having threaded perforations, bolts inserted through theperfora tions of the lia-nge and ring for holding `the boltsl in. placeand the ring against the `flange, a Wheel telesooped over the hub memberhaving perforations adjacent the center through which the bolts areinserted, and removable fastening means atthe outer .ends of the boltsto hold the Wheel in place against the ring.` l

In a demountable Wheel, the eombination ,with a hub member having aperforated flange, of a. ring having threaded per-fora tions,bolts'in'serted through the perforations of the flange and ring forholding'the bolts inplaoe and the ring against the iiange, v

a Wheel Iteleseoped over the hub member having perforations adjacent thecenter through which the bolts are inserted, and removable fasteningmeans at the outer ends of the bolts to hold the Wheel in place .againstthe ring, said means comprising a perforatedmetal plate and nuts at-theends of the bolts to 4enga-ge against theplateto clamp the vvheelvbetween it and the said llnu.

f'The combination with a flanged Wheel hub having nnthreadedperforations in the flange, of a ring with threaded erforationscorresponding to those of the ange, bolts inserted through the holes ofthe liange and.

threaded into the holes of -thering todraw it tightly'against theyflange thereby holding the-bolts in place, a Wheel telescopeduover thehub having perfor-ations to fit over the bolts, a plate secured to theouter sidefof the wheel having a perforation to it'overv the hub andother perforations through! which the bolts also extend, and fastening.nuts attachedto the ends .of the'bolts` and ing the Wheeln j'place.

-- 5. ln a demountable wheel, the combination with' a hub having aAperforated flange of 'a ring having corresponding threadevperforations, bolts extended through -the perfor-ations of the saidring, means for f holding the bolts in place' in the ring, a Wheellsecured to the bolts, and a eedomete'r gear attached to the said ringeyond the.' outer edge of the ange. v 1

In testimony whereof I have signed my name to this specification on.this 17th day of March, A. D. 1917. f l' xsane N. WHITE.
